[Moved] retrieve variable from XML and show in text field

[rajan.mba]

Hi
I need some help with Qt and XML. I retrieve the latitude from google API using
@XmlListModel {
// property int index
id: latModel
source: "http://maps.googleapis.com/maps/api/geocode/xml?address="+city+"&sensor=false"
query: "/GeocodeResponse/result"
XmlRole { name: "lat"; query: "geometry/location/lat/string()" }
XmlRole { name: "lng"; query: "geometry/location/lng/number()" }
XmlRole { name: "addr"; query: "formatted_address/string()" }
}@
However when I use it to retrieve the 'lat' variable to put in text, I get 'ReferenceError: Can't find variable: lat'. I am able to use the same variable in a list view without any problem. Pl let me know how to retrive the variable 'lat' and display in the text field.
@Text {
id: lattxt
x: 10
y: 200
width: 100
height: 30
color: "#360414"
text: lat
font.bold: true
font.pixelSize: 40
}
@
THANKS IN ADVANCE

You can not use XmlListModel in this way. A model is supposed to be used with a view, and the XmlRoles will be made available to delegates in that view. Outside of that scope, it is meaningless.

Try putting your text item in a listview as a delegate that changes the text per the docs:

@
XmlListModel {
id: xmlModel
source: "http://www.mysite.com/feed.xml"
query: "/rss/channel/item"

 XmlRole { name: "title"; query: "title/string()" }
 XmlRole { name: "pubDate"; query: "pubDate/string()" }

}
@

@
ListView {
width: 180; height: 300
model: xmlModel
delegate: Text { text: title + ": " + pubDate }
}
@

Of course you use your text and xml role in the example.

The example for the QML Twitter project is a good illustration as to how XML Roles get displayed.

Thanks for the reply. I will look into it. Sorry I didn't notice the QML thread so I posted my question under Qt.

Basically you can do as advised though this is far from optimal...

@XmlListModel {

source: "http://xkcd.com/100/";
query: "/html/head"
namespaceDeclarations: "declare default element namespace 'http://www.w3.org/1999/xhtml';"

XmlRole { name: "image"; query: "title/string()" }

onStatusChanged: {
    if (status == XmlListModel.Ready)
        titleText.text = get(0).image;
}

}

Text {
id: titleText
}@
